Alrighty then, I just read thoroughly about the coolants. So i can go buy some prestone prediluted and I wont have to add the distilled water? llool!! It is only looking a little low. Oh and I do put it in where it says coolant in the middle car at the very back right? That is the only place I see. There is no spot on the radiator as someone was saying on what they thought was on the 540. They were wrong.
